I think he may have a few years ago (before the last Presidential election). Or at least, he claimed Him as his Savior.
It was a weird interview/pronouncement. You could tell that he was just mouthing the words as rote. His heart wasn't in it, and he didn't believe what he was saying.
But he had to get it out there for the contingent of his followers who claim to be Christians, to feel comforted for voting for an anti-Christ.
